"And whenever you fast, do not put on a gloomy face as the hypocrites do, for they neglect their appearance in order to be seen fasting by men. Truly I say to you, they have their reward in full. But you, when you fast, anoint your head, and wash your face so that you may not be seen fasting by men, but by your Father who is in secret; and your Father who sees in secret will repay you."

Just something to keep in mind.
